How to install the Object Modelling System Console on Windows 10

1) Download openJDK 8 LTS from

2) Install it

3) Open a command prompt and run the command:
java -version
It should return:
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

4) Download the Object Modeling System console version 3.6.28 from

5) Unzip the Object Modeling System console and run the console.bat file

6) In the console setting, select the panel Run and set the Java path (see screenshot) to the previously installed JDK which usually is:
C:\Program Files\AdoptOpenJDK\jdk-8.0.232.09-hotspot
(please check the correct JDK version first)

GEOframe Winter School 2020 - It is time to apply !

The second edition on the Winter School on GEOframe will be held between January 8 and 17, 2020 in Trento, Italy.  The course is devoted to Ph.D. Students, Post-docs, Young researchers (and Professionals!) interested in estimating all the components of the hydrological cycle (rainfall, evapotranspiration, snow-melting, and river discharge).  The system they will learn allows to work out very small catchments and continental basins as well (e.g. Abera et al., 2017a,b) up to build operational solutions as the one used in in Basilicata.

The aim of the course is to enable participants to run their own simulations and eventually on their own catchments and estimate the hydrological budget components.
With respect to the 2019 Winter School, there will be more practice and more detailed work on evapotranspiration and rainfall-runoff. It will be much more focused on exercises and on getting the water budget performed under various hypotheses on models' structure.


Website for the enrollment go here.

 For the hole definitive material of the School go here. 

The provisional topics will be:

Teachers will be:

Prof. Riccardo Rigon, Ph.D.
Prof. Giuseppe Formetta, Ph.D.
Marialaura Bancheri, Ph.D.
Niccolò Tubini, Ph.D. student



The topics (links added after the School):

To have an idea of the topics, the interested researchers should give look at the material (slides, video etc. of the 2019 Winter School).  The material of the first three days remains very similar (but refined) to the old one. Therefore, for students is possible also to participate only to the second week (at the same cost, but saving some lodging) but, in that case, is mandatory to follow the on-line courses and tutorials  relative of 8-9-10 January topics and having done the exercises before December 15. We will offer prompt online support to them up to that date and no support whatsoever on the same topics later or  between 13-17 of January for clear reasons of course efficiency and organisation.  The refined material of the first three days will be available on the Winter School website  from November 15, 2019.

With respect to the 2019 School, there will be more practice and more detailed material on Evapotranspiration and Rainfall-Runoff. For every 40 minutes of talk there will be 70 minutes of supervised exercise for a total of 8 hour a day of activities. 

Cost of the School is 350 Euros for who will subscribe before November 15, 400 Euros for others. A discount of 20 Euros is granted to fellows of the Italian Hydrological Society (subscriptions for students are available at the IHS-SII site for 10 Euros to students and 20 to seniors). Who attended the last year school can participate free of charge, upon subscription. Inclusive of the costs will be coffee breaks and lunch at the Cafeteria of Department of Civil, and one social dinner for all the schoolmates Environmental and Mechanical Engineering. 

Website for the enrollment go here.

Material for the Winter School on the GEOframe System - Installations

The Winter School on the GEOframe system is approaching.  In this webpost you will find all the preparatory material of the school indexed.

Installations

You are not assumed to know Python or Java to participate to the School. However programs runs on Java.. We will not do any Java programming though.  Input/Output of models will be treated by using some scripting in Python. We will communicate the appropriate notions during the classes. However, for the interested there are plenty of courses on the web (for instance this comes from SciPy 2018. Other from SciPy here.)
  • Java. GEOframe and OMS are written in Java and they require to have installed Java on your computer. Here you can find instructions to install Java on your computer.  OMS need Java 8 JDK.  Please note that you need the Java Development Toolkit (JDK) installed not the Java Runtime Environment (JRE).  The official Oracle's pages are here. You can watch several videos for Windows: here. Googling you can get videos for your platform.
  • We are going to use Docker for our modelling. Therefore you need to install it (here for Linuxes) on your computer. To quickly understand what Docker is, you can see here. Or read this tutorial. This video could be useful too. The knowledge of Docker required will be extremely elementary. You will not be required to do Docker applications. You simply use one and, at the end, is just matter of executing a command. 
  • During the School we will use Jupyter and Python 3 for data management and visualisation. It would be great if you could arrive
    • The post at this link contains all the information needed. For installation of the software, we suggest Anaconda. For any problem contact us through the mailing list. 
    • To understand what a Jupyter notebook is about, please see its manual. However, we will use Jupyterlab.  (You can see a YouTube video about here).  One can think that Jupyter was heavily based on the look-and-feel of Mathematica notebooks: but Jupyterlab is a step ahead to something different. Installing Anaconda, you also have already installed Jupyter notebook. So you have just to try it issuing the command: 
      • Jupyter notebook
  • You still do not know what to do with it, but we will lear step by step during the Winter School
  • Finally, at least for MacOs user, due to a bug either in the Docker or in GEOtools, it is necessary to use the OMS Console.  You can download the beta 3.5.62 release from here.
  • If you want to further with Jupiter and Jupiterlab, you can  install BeakerX. For its installation, please follow verbatim the instructions here. The instructions given at the main page of BeakerX are incomplete ;-).

Winter School on the GEOframe system

The course for doctoral students, post docs and young researchers in Hydrology, Forestry, and related disciplines will cover the simulation of the hydrological cycle of catchments of various sizes with the GEOframe system. To know about GEOframe and GEOframe-NewAGE, please refer to here.

They say that all models are wrong but useful. However, with better tools you forecast and decide better.

The course will enroll at most thirty students and will be held at the Department of Civil, Environmental and Mechanical Engineering of Trento from January 8 to January 18 included.
The course will be of totally 68 hours (8 a day) of which 34 (4 each day) will be dedicated to laboratory and personal work under the supervision of tutors. The course includes as option to get an exam certification, upon the completion of an exercise, to have doctoral credits.

Instructors

  • Riccardo Rigon
  • Michele Bottazzi
  • Niccolò Tubini
with material prepared by
  • Giovanna Dalpiaz
  • Marialaura Bancheri


The  topics treated has been:


Why choosing GEOframe over other models/platforms ? I would say for:
  • Flexibility: GEOframe is not a model but a system of components that interact at run-time. You can chose among various components options for any of the processes.
  • Expandability: If you like to program, with a little investment in Java you can write your own component and make them to interact with the others without having to reinvent the wheel.
  • Parallelism. Components work in parallel when their tasks do not interact, but this is transparent for you (we call it implicit parallelism). 
  • Spatial discretisation. A catchment is subdivided in parts (HRU) which can be modeled separately and are computed in parallel. The network structure is used to achieve the spatial parallelism. Its spatial modularity can be used to add/cut part of the basins without having to redo the spatial analysis, for doing multisite calibration, to progress the analysis of a larger basin in parts that are assembled together eventually.
  • Beyond-state-of art components.  Besides traditional approach to processes, we implemented a few new ideas for all the processes we covered.
  • Reliability.  GEOframe is currently used for the flood forecasting in real time by Regione Basilicata. It is not just a system for research that does not work in real cases. 
  • Tracers studies. Not treated in the school are present tools for doing tracers studies,
  • Process based modelling.  Not treated in the school, we have tools for integrating Richards equation in 1D, and we are developing tools for integrating it in 2d and 3d coupling it with the energy budget. These components will be able to interact with the other. We also started new developments on freezing soil and snow modelling.

The cost of the course for early subscribers is 270 Euros which includes lunch and parsimonious coffee-breaks  Member of SII, The Italian hydrological Society have a discount of 20 Euros. Cost of late subscribers (after November 15, 2018) is 370 Euros. 

After November 15 some work will be required to participant in order to setup their tools for running GEOframe. Installation of Java (version 8), installation of the Object Modelling System console, Installation of Python and Python notebooks, testing the use of some file formats. After the accomplishment of the requirements, students will be allow to bring their own study cases at the School.
